Henrich Rademacher married to Maria Gertrude Esch

Henrich b. approx 1803; Maria b. approx 1811. Their daughter Anna Apollonia Rademacher was born in 1841 Prussia. She was the 2nd wife of John Peter Pohl, married 9 Jan 1866 & residing in Westphalia, Clinton County, Michigan. If anyone knows this line, I am desperately trying to find if they had a child named Nicholas Pohl (b. Oct 1866 in Clinton Co, MI) &/or any other children. Thanks in advance for any help!
